We can apply the M-treatment to any steel grade. We use a calcium treatment to modify the non-metallic inclusions and we closely regulate the levels of calcium, oxygen and sulphur. We do the modification of the inclusions in such a way as to maximize machinability and improve fatigue strength.
A protective layer forms on the cutting tool during machining of M-Steel that significantly reduces the wear on the tool and increases the tool life. At every stage in the M-Steel production process, we optimize the material for improved machining; from raw material through melt, to casting, hot rolling and the final heat treatment. We can meet individual delivery requirements and supply the material in the form that is best for your machines in compliance with tight straightness and dimensional tolerances. M-Steel has a consistent machinability from cast to cast meaning that the machines can run on consistent high cutting speeds and with predictable tool change intervals from one production run to another. Recent findings also show that the M-Steel effect is particularly effective in turning in very hard condition using Cubic Boron Nitride (CBN) inserts.
The replacement of traditional grinding of case- and induction hardened surfaces with hard part turning can mean very large cost savings together with production lead-time and quality improvements.
The M-Steel Calculator.
The M-Steel Calculator is a tool that will help you choose the right cutting set-up depending on your cutting tool and the material used. You will also get specific information on machine power; chip stream and the expected surface quality of your material. The M-Steel calculator will also calculate the difference between these parameters when using M-Steel and a conventional steel. When using M-Steel you will normally be able to save up to 30-40 % in production cost without losing any of the improvement in machining.
